Question

我有一台Mac，并已将py.test安装到Python 3库（而不是Apple的标准Python 2.7库）。这是因为我使用的是Python 3。

但是，当我在PyDev中运行py.test时，会发生以下错误。关于如何解决这个问题的任何解释？我已经考虑了这个问题很长一段时间了。

注意：我已经在LiClipse中安装了PyDev。我根据文档配置了py.test测试运行器：

--maxfail=2 --tb=native

然后我根据py.test的文档运行了一个简单的py.test测试文件：

def func(x):
    return x + 1

def test_answer():
    assert func(3) == 5

pytest配置似乎是正确的。

所以，有些事要检查：

可以使用py.test filename在命令行（LiClipse外）运行吗？
您究竟如何运行测试？（在该文件上按Ctrl + F9还是运行文件夹？）

错误似乎是在评估pytest中的标记时（即：pytest.mark.xxx），是否有可能在项目的其他部分有一些无效标记？

在PyDev中配置py.test（Python 3，Mac）
